MACHINE FOR FORMING CHECK-ROWER WIRE.

SPECIFICATION forming part of Letters Patent No. 314,106 dated March 17,1885.

Application filed October .27, 1883. (No model.)

1'0 all whom it may concern.-

Be it known that I, GEORGE W. CAYWOOD, a citizen of the United States,residing in Joliet, county of WVill, and State of Illinois, 5 haveinvented certain new and useful Improvements in Machines for FormingCheck- Row Wire, of which the following is a specification.

I My invention relates more particularly to im'provementsin machines formaking checkrower wire for which United States Letters Patent,'No.291,584, were granted to George B. Durkee on the 8th day of January,1884, and assigned to the J oliet Wire Check Bower Gompany, to whichsaid company the invention embodied in this application has beenassigned by me.

The object of my invention is to provide the machine with novel meansfor guiding the end of the wire fed forward by the feedcarriage underthe mandrel upon which the loops are made, whereby while one end of thewire at the point where it has been severed by the cutter at one side ofthe mandrel shall lie upon the mandrel, the other opposing'terminalshall be accurately guided under the mandrel, for the purpose set forthin the said application.

A further object is to provide a gage mech- 0 anism which shall allowthe wire to be drawn through the machine after the formation of eachknot or check to a certain extent only, whereby the checks shall beformed at regular intervals along the wire; also to provide novel 5means for guiding one end of the wire under the mandrel after the wirehas been cut and while the feed-carriage is beingadvauced; also toprovide, in combination with the vibratory throw-lever situated at thedelivery end of the 0 machine, an intermittiugly-operating clampthemachine by the throw-lever, whereby when a check reaches a certain partof the gage mechanism the movement of the wire shall be arrested, all ashereinafter described and claimed, and illustrated in the annexeddrawings, in which Figure 1 is a top or plan view of the machineconstructed as in said prior application with the addition of theimprovements here- 63 inafter set forth. Fig. 2 is a perspective viewofa portion of the said machine, and shows my improved mechanismforguiding one part of the wire under the mandrel after the cut has beenmade. Fig. 3 is asection taken trans- 6 verse'ly through a portion ofthe end of the machine, said view showing the table-support, in dottedlines and illustrating means employed for clamping and holding the wireat the delivery endof the machine during the V back throw of thethrow'lever. Fig. 4 is a detail side elevation of the delivery-endportion of the machine, and shows a gage mechanism for catching andholding the wire at a pointjust in advance of a knot or check during thecutting, looping, and coiling operations, or during so many of suchoperations as may be required. Fig. 5 is afperspective View of theforked end of the gage-lever, shown in Fig. 4 as adapted to catch thewire at one end of the knot or check. a

I have hereinbefore observed that the devices constituting thesubject-mattcr of this application are applied to a machine constructedand operating upon the principle of 85, y the machine embraced inanother patent. In order, therefore, to impart a clear understanding ofmy present invention, I shall proceed to incorporate a brief descriptionof the construction and operation of the machine dc o. scribed at lengthin'said former patent, and in the present description of the machine Ishall use for reference the same capital letters and numbers as areemployed in the former patent to indicate corresponding parts, anddenote the novel members by small letters, it I beingunderstood thatthespecification and drawings of said former patent will furnish acomprehensive description and illustration of all of the details of themachine, excepting red those that form the subject of this case.

The letter A indicates the bed or'table of the main frame of themachine, and the nu merals 1 2 3 4 5 respectively refer to the wheelsprovided with cam-grooves and in part with mutilated gears, for thepurpose of intermittingly actuating the various members of the machineat the proper moments, as fully set forth in said prior patent.

The wire 10, shown passing through the machine in the plan view Fig. 1,is first severed into two parts at a point between the mandrel D and thecombined guide and rotary coiler E by means of a vibratory cuttingmechanism, B, which moves forward and severs the wire and then movesback out of the way. After the wire has been thus cut, one part of thewire remains resting upon the mandrel and the feed-carriage O advances,so as to pass the end of the remaining part of the wire under themandrel, in order to allow the two parts to be crossed by means of asubsequent forward movement of the mandrel and bar, carrying the mandrelin a direction at right angles to the line of feed.

In said former application the means for gripping the wire on thefeed-carriage when the latter was movedforward, and for releasing thewire when the carriage was retracted, consisted of two spring-controlledjaws, 23, pivoted upon the carriage and limited in their movement in onedirection by means of stops. Other suitable means for such purposecould, however, be employed, and no claim is made to such in thisapplication.

The first feature of my invention relates to means for guiding under themandrel the forward end ofthat part of the wire carried by theiced-carriage when the latter is advanced and the wire fed forwardthrough the combined guide and coiler E. For such purpose I provide avibratory guide,f, Fig. 2, consisting of an arm pivotally suspended froma standard, f, supported upon the block or support 28,

- through which the horizontal rack-bar 27, carrying mandrel D, and abar, 93, carrying the stripper I, work. This arm is provided at itsfwmnlower end with anotch or a pair of fiat fingers,

f set at such angle that when the arm is swung forward the free end ofthat part of the wire fed forward by the feed-carriage shall be caughtbetween the fingers, which, when in or substantially in their lowestposition, shall de press the end of the wire sufficiently to guide itunder the mandrel as the wire is fed forward. This vibratory guide f isoperated from a cam projection, g, on the wheel 2, when said camprojection strikes the cranked end of a rock-shaft, 9, supported insuitable bearings on the main frame and provided at one end with anupright arm, 9", which connects by a link, 9 with the vibratory guides.The cam projection on the wheel is timed to operate this guide-actuatingmechanism after the wire has been severed by the cut-ting mechanism, soas to swing the guide forward and to liberate the crank-arm of suchmechanism after the wire has been guided under the mandrel, so as toallow any suitable weight or spring attached to an arm, 9, on therock-shaft g, to reversely operate such mechanism, and thereby swingback the guide. After this opera tion, the mandrel advances and theshoulder on the bar carrying the mandrel pushes the ends of the wire toone side, so as to cross them. The rotaryloopcr F is then brought intoaction, and by a rotary movement bends the ends of the wire into a pairof connected loops. The feed-carriage and the mandrel then move back totheir first positions, during which said retraction on the part of themandrel the looper F advances, whereby the looped ends of the wire heldupon the mandrel between the looper and the bar carrying the mandrel arebrought into the line of feed. The two carriages 4.6 and 76,respectively carrying the rotary coilers E and G, also ad vancesimultaneously toward each other, and when. brought up to the work andin the proper position to engage the terminals of the wire back of theloops rotate in reverse directions, so as to coil the wire upon itselfback of the loops, and thereby form the checks or shoulders. After thecompletion of these checks or shoulders and the rotation of the coilershas ceased, the carriages carrying the coilers move apart and recedc totheir first positions. \Vhen the carriage carrying the coiler G reachesthe limit of its back move ment, part 84 of the clutch carried by saidcarriage engages the permanently-located clutch-section 85, so that whenthe clutch is rotated the loosering-gear 78, engaging the sliding-jaws62 63 of the coiler G, will, through the medium of certain connectionsset forth in the former application, cause said jaws to open, andthereby allow the knotted or check portion of the wire to be drawnbetween the jaws and through the machine by means of the vibratorythrow-lever,which, as set forth in said prior application, will belocated beyond the delivery end of the machine and actuated from wheel 5by mechanism so timed that after the jaws of coiler G have been openedthe throw-lever shall swing away from the machine, and in so doing antomatically grip the wire and draw the same forward, and afterwardrelease the wire and swing back toward the machine in position to againgrip and draw forward the wire after the next operation of the machine.Thejaws of coiler G are automatically closed after the wire has beenthus drawn through the ma-' chine, after which the operation of forminga check is repeated.

In order to effectively hold the wire during the several steps oroperations prior to drawing it through the machine, I provide at thedelivery end of the latter a clamp, which, after the wire has been drawnforward to the required extent by the throw-lever shall grip the wireand thereby prevent it from being pushed backby the throw-lever when thelatter, after releasing its hold on the wire,is moving back to get anewhold on the wire, so that at its next forward movement it can againtoo IIC

draw forward the wire. The clamp also serves to hold the wire during thecutting, looping, and coiling operations, and the back movements of thecarriages. This clamp is simply composed of a slidable bar or jaw, h,pivotally connected with a vibrating lever, h, supported at one end ofthe machine and provided on its lower arm with a stud or roller, It,held in the path of acam projection, h, on wheel 5 by means of a spring,h, said cam projection being timed to actuate the vibratory arm afterthe throw-lever has been swung forward, and to thereby cause the jaw hto slide forward and hold the vvire against one of the walls of aguide-recess, 71?, through which the wire passes. This guide-recess isconveniently formed by a metalbox or casting, h, secured upon the tableand provided with a bearing for the slidable jaw.

The duration of the clamping action of the jaw'upon the wire is ofcourse limited to the length of the cam projection, which can be variedas may be deemed expedient.

In the machine embraced in the said prior application, the length ofwire drawn through the machine by the throw-lever, and consequently thedistance between the checks,is determined by the extent of throw of thesaid throw-lever. In order to, however, more accurately regulate thedistance of the checks from each other, and to insure with more eertainty a determinate length of wire being drawn through the machineafter the formation of each knot or check, I have provided a vibratorygage-lever, i, pivotally supported at one end (at the delivery end ofthe machine) and provided at its free or outer end with a fork or pairof fingers, 6", adapted to embrace the wire when the lever is swung downinto substantially a horizontal position. This gagelever is raised andlowered by means of a pitman, 7:, provided at its lower end with aroller, Z, which bears upon a camfaced wheel, m, that is arranged andadapted to lift the pitman at the proper moment in order to raise andfree the gage-lever from the wire, and to allow the pitman andconsequently the gage-lever to drop at the required time, so that thefork of the latter shall ongage the wire that is to be drawnforward bythe throw-lever. When, therefore, the throwlever draws the wire forward,it will at the proper moment be arrested by reason of the check comingin contact with the forked end of the gage-lever, as in Fig. 4, wherebythe wire cannot be drawn to any further extent until the gage-lever hasbeen again raised. The forked end of the gage-lever is made adjustable,so as to regulate the distances between the checks, and to such end thelever can be composed of two parts having perforations n, through whichscrews or bolts can be passed for the purpose of securing said partstogether after the outer part carrying the fork has been properlyadjusted upon the inner part of the lever.

I In said Fig. 4, the numeral 56 denotes the inclined shaft carrying twobevel-gears, 57, the upper one of which is provided for engaging a gear(not herein shown) as a means for operating the clutch mechanism whilethe lower bevel-gear engages a bevelgear, 55, fixed on a shaft carryinga pinion, 54, which is at intervals operated by a mutilated gear onwheel 5; also, 106 denotes the pitman employed for operating thethrow-lever, and 108 the crank connected with said pitman and fixed upona shaft carrying a gear, 105, cugaging a gear, 104, that is in turnfixed on a shaft carrying a pinion that is driven from said wheel.

It is understood that my improvements can be used on a machineconstructed as shown in the drawings of the before'mentioned patent, orupon a machine adapted to perform the functions therein set forthin thespecification in such case.

Having described my invention, what I claim, and desire to secure byLetters Patent,
